  1. Agents of change, The Economist Next Article Bookmark and Share

    Excerpt: Conventional economic models failed to foresee the financial crisis. Could agent-based modelling do better? (...)
    Agent-based modelling does not assume that the economy can achieve a settled equilibrium. No order or design is imposed on the economy from the top down. Unlike many models, ABMs are not populated with “representative agents”: identical traders, firms or households whose individual behaviour mirrors the economy as a whole. Rather, an ABM uses a bottom-up approach which assigns particular behavioural rules to each agent. For example, some may believe that prices reflect fundamentals whereas others may rely on empirical observations of past price trends.

  2. Link communities reveal multiscale complexity in networks, Nature Next Article Bookmark and Share

    Excerpt: Here we reinvent communities as groups of links rather than nodes and show that this unorthodox approach successfully reconciles the antagonistic organizing principles of overlapping communities and hierarchy. In contrast to the existing literature, which has entirely focused on grouping nodes, link communities naturally incorporate overlap while revealing hierarchical organization. We find relevant link communities in many networks (...)

    1. Stability of Ecological Communities and the Architecture of Mutualistic and Trophic Networks, Science Next Article Bookmark and Share

      Abstract: Research on the relationship between the architecture of ecological networks and community stability has mainly focused on one type of interaction at a time, making difficult any comparison between different network types. We used a theoretical approach to show that the network architecture favoring stability fundamentally differs between trophic and mutualistic networks. A highly connected and nested architecture promotes community stability in mutualistic networks, whereas the stability of trophic networks is enhanced in compartmented and weakly connected architectures. These theoretical predictions are supported by a meta-analysis on the architecture of a large series of real pollination (mutualistic) and herbivory (trophic) networks. We conclude that strong variations in the stability of architectural patterns constrain ecological networks toward different architectures, depending on the type of interaction.

  3. Emergence of Zipf's Law in the Evolution of Communication, arXiv Next Article Bookmark and Share

    Abstract: Zipf's law seems to be ubiquitous in human languages and appears to be a universal property of complex communicating systems. Following an early proposal made by Zipf concerning the presence of a tension between the efforts of speaker and hearer in a communication system, we introduce evolution by means of a variational approach to the problem based on Kullback's Minimum Discrimination of Information Principle. Using a formalism fully embedded in the framework of information theory, we demonstrate that Zipf's law is the only expected outcome of an evolving, communicative system under a rigorous definition of the communicative tension described by Zipf.

  5. Citizen science: People power, Nature Next Article Bookmark and Share

    Excerpt: And it works. This week, Baker and his colleagues publish evidence that top-ranked Foldit players can fold proteins better than a computer. By collaborating, these top players often come up with entirely new folding strategies. "There's this incredible amount of human computing power out there that we're starting to capitalize on," says Baker, who is feeding some of the best human tactics back into his Rosetta algorithms.

    1. Predicting protein structures with a multiplayer online game, Nature Next Article Bookmark and Share

      Excerpt: People exert large amounts of problem-solving effort playing computer games. Simple image- and text-recognition tasks have been successfully ‘crowd-sourced’ through games1, 2, 3, but it is not clear if more complex scientific problems can be solved with human-directed computing. Protein structure prediction is one such problem: locating the biologically relevant native conformation of a protein is a formidable computational challenge given the very large size of the search space.

  6. The makings of great leaders, Nature Next Article Bookmark and Share

    Excerpt:
    Our obsession with the personalities of great leaders is out of kilter with the scientific basis of social hierarchies, according to two books. In The New Psychology of Leadership, psychologists Alexander Haslam, Stephen Reicher and Michael Platow propose that successful stewardship owes more to the good relationship between a leader and his or her followers than to an individual's character. In Selected, psychologist Mark van Vugt and journalist Anjana Ahuja take an evolutionary approach, suggesting that leadership emerged to aid the survival of small communities on the African plains.

  7. Meaning in a Quantum Universe, Science Next Article Bookmark and Share

    Excerpt:
    What is reality? Why is there anything at all? How did the complexity of the universe arise? What do quantum mechanics and quantum computers have to do with all this? If you have ever pondered any of these questions, then Vlatko Vedral's Decoding Reality is for you. Well written and engaging, the book provides a constant flow of new ideas. Vedral (a physicist at Oxford University) attempts to explain all of reality, its origins, and evolution in terms of the concept of information. He starts with Shannon's communication theory and then turns to quantum information theory and quantum computing. These are weighty topics, yet Vedral elucidates normally inaccessible concepts and theories with ease.

  8. Getting Better To Get Bigger, Science Next Article Bookmark and Share

    Excerpt: The end of the age of fossil fuels may be in sight, but what comes after is still a bit of a blur. There are numerous alternatives to coal, oil, and natural gas from electricity generated by solar farms to biofuels brewed from plants. Scaling up these alternative sources of energy, however, has proved a challenge. This special issue explores the progress that researchers are making in developing better alternatives, and the technical, political, and economic pitfalls associated with scaling them up.

  9. Ecology: Close relatives are bad news, Nature Next Article Bookmark and Share

    Excerpt: Simple models of competition among species suggest that a few tree species, those that are best at exploiting limiting resources such as light and nutrients, should dominate ecosystems such as tropical rainforests. However, rainforests support hundreds of apparently very similar tree species " typically a small number of abundant species and many rare ones. How do these species coexist? Why are some of them rare and others common? Complementary studies in Panama by Comita et al. and Mangan et al. show that a form of negative feedback driven by soil organisms can explain the relative abundance of tropical tree species, as well as promoting their coexistence.

  10. Cancer biology: Blood vessel regulator, Nature Next Article Bookmark and Share

    Excerpt: Growing tumours rely on a good blood supply to feed them, so the identification of a small RNA molecule that switches on blood-vessel growth in tumours provides a potential target for anti-cancer drugs.

  11. Which Parental Gene Gets the Upper Hand?, Science Next Article Bookmark and Share

    Excerpt: Things used to be relatively straightforward when it came to parental influences on gene action. Mom and Dad passed on one copy (or allele) of each autosomal gene to their progeny and overall, the expression and function of genes inherited by the offspring were indifferent to which parent they came from. When imprinted genes were discovered, this simple picture changed. That is because chemical modifications of DNA that occur early during development of the female and male germ line (the cells that form the egg and sperm) epigenetically mark imprinted genes for differential expression, depending on whether the gene is of maternal or paternal origin. In some cases, such imprinting suppresses expression from the maternal allele, leading to sole (or predominate) expression of the paternal copy of the gene. For other imprinted genes, the opposite is true and expression is solely or predominately from the maternal allele.

  12. Rewarding altruism, SFI Working Papers Next Article Bookmark and Share

    Abstract: In this work we examine studies from different disciplines which lead us to hypothesize that human altruism can be intrinsically rewarding and, given its plasticity, is modulated by social contexts. We address several investigations on neural and endocrine processes, as well as the beneficial effects that altruistic behaviour and social support have on immunity, life expectancy and stress levels, among other advantages. Considering this evidence, we propose a model of social cooperation that presents phase transition in an imperfect supercritical pitchfork bifurcation. The manuscript proposes a potential beneficial role of altruism that could account for its occurrence among non-kin and beyond reciprocity. The model presented here allows the experimental testing of this hypothesis under different cultural and social conditions. This contribution sheds new light on the theoretical discussion about the origin and development of altruism in humans.

  13. Microbial Biosynthesis of Alkanes, Science Next Article Bookmark and Share

    Abstract: Alkanes, the major constituents of gasoline, diesel, and jet fuel, are naturally produced by diverse species; however, the genetics and biochemistry behind this biology have remained elusive. Here we describe the discovery of an alkane biosynthesis pathway from cyanobacteria. The pathway consists of an acyl"acyl carrier protein reductase and an aldehyde decarbonylase, which together convert intermediates of fatty acid metabolism to alkanes and alkenes. The aldehyde decarbonylase is related to the broadly functional nonheme diiron enzymes. Heterologous expression of the alkane operon in Escherichia coli leads to the production and secretion of C13 to C17 mixtures of alkanes and alkenes. These genes and enzymes can now be leveraged for the simple and direct conversion of renewable raw materials to fungible hydrocarbon fuels.

  14. Salamander's egg surprise, Nature Next Article Bookmark and Share

    Excerpt: Scientists have stumbled across the first example of a photosynthetic organism living inside a vertebrate's cells. The discovery is a surprise because the adaptive immune systems of vertebrates generally destroy foreign biological material. In this case, however, a symbiotic alga seems to be surviving unchallenged " and might be giving its host a solar-powered metabolic boost.

  15. Timing matters: Lessons From The CA Literature On Updating, arXiv Next Article Bookmark and Share

    Abstract Excerpt: In the present article we emphasize the importance of modeling time in the context of agent-based models. To this end, we present a (selective) survey of the Cellular Automata-literature on updating and draw parallels to the issue of agent activation in agent-based models. By means of two simple models, Schelling's segregation model and Epstein's demographic prisoner's dilemma we investigate the influence of choosing different regimes of agent activation. Our experiments indicate that timing is not a critical issue for very simple models but bears huge influence on model behavior and results as soon as the degree of complexity increases only so slightly. After a brief review of the way commonly used ABM simulation environments handle the issue of timing, we draw some tentative conclusions about the importance of timing and the need for more research towards that direction, similar to the concerted effort on updating in cellular automata.

  16. Phase synchronization in railway timetables, Eur. Phys. J. B Next Article Bookmark and Share

    Abstract: Timetable construction belongs to the most important optimization problems in public transport. Finding optimal or near-optimal timetables under the subsidiary conditions of minimizing travel times and other criteria is a targeted contribution to the functioning of public transport. In addition to efficiency (given, e.g., by minimal average travel times), a significant feature of a timetable is its robustness against delay propagation. Here we study the balance of efficiency and robustness in long-distance railway timetables (in particular the current long-distance railway timetable in Germany) from the perspective of synchronization, exploiting the fact that a major part of the trains run nearly periodically. We find that synchronization is highest at intermediate-sized stations. We argue that this synchronization perspective opens a new avenue towards an understanding of railway timetables by representing them as spatio-temporal phase patterns. Robustness and efficiency can then be viewed as properties of this phase pattern.

  18. Performance, Not Control, Science Next Article Bookmark and Share

    Excerpt:
    Standard histories and critiques have given us an image of cybernetics as a dry, foreboding, militarist science of command and control. The word cybernetics itself derives from the Greek word kybernetes ("governor" or "steersman"), and until now the paradigmatic case for the science of steersmanship has been the U.S. context, where cybernetics emerged in the wake of the Second World War. While the American case has received much attention from historians, the same cannot be said of British cybernetics. By focusing on the developments in Britain, Andrew Pickering's The Cybernetic Brain: Sketches of Another Future opens wide new vistas for exploring cybernetic practice and its legacy.

    2. Absolutely Small: How Quantum Theory Explains Our Everyday World, AMACOM Next Article Bookmark and Share

      Summary:
      How a photon can be in two places at once is just one of the conundrums of quantum physics that Fayer helps to unravel. The Stanford University Professor provides a roadmap for non-scientific readers who wish to understand the subject but lack advanced mathematical training. Fayer's belief that our everyday experiences "teach us to think in terms of classical physics" helps him easily breach the leap from playing ball to understanding how the earth orbits the sun. (...) Fayer illustrates the ways in which "the natural world is driven by quantum phenomena" with an accessible treatment of a fascinating subject.
